The dataset is compatible with the UCDP/PRIO Armed Conflict Dataset (Gleditsch et al., 2002; Harbom & Wallensteen, 2009) for the period 1946–2008. Version 2.0 is compatible with the Correlates of War Dataset (Sarkees, 2000) for the period 1900–97; and the Fearon & Laitin (2003) dataset on civil conflict in the period 1945–99. Since the Correlates of War and Fearon & Laitin datasets have not been updated, we refer to Version 2.0 for data and documentation relating to these two datasets.

Users should contact battledeaths@prio.no with any comments or corrections. We will try to reply to your e-mail as soon as it is received, but all e-mails will be collected in a special account and reviewed when we next update; probably in 2011. Suggestions for new and improved sources of battle death information are welcome. Version 3.0 of dataset does not include a list of battle deaths by participants. Users in need of such data should consult Version 1.0.
